Which IOS command is used to initiate a login into a VTY port on a remote router?
A.
router# login
B.
router# telnet
C.
router# trace
D.
router# ping
E.
router(config)# line vty 0 5
F.
router(config-line)# login
Explanation:
VTY ports are telnet ports hence command B will initiate login to the telnet port.
It’s one of those confusing questions again..uhh!
When in doubt, it works to eliminate all the incorrect answers 😉
answer A is incorrect because: the login command has to be used at the line config level (like in answer F)
answer C is incorrect because the complete command is traceroute
answer D is incorrect because the command ping is used to test if a host is reachable
answer E is incorrect because it is the command you use to get into line config mode
answer F is incorrect because with this command you “activate” the login process for the vty or console line
which only leaves B as the correct answer
Understanding what they’re asking is the hardest part. If understand the question, the answer becomes simple…
